Question

Find x and y if (x+1, y–2) = (3, 1).​

Answer 1

Step-by-step explanation:

x+1 = 3 => x = 2

y-2 = 1 => 6 = 3

Answer 2

S O L U T I O N :

Finding value of x :

${:}\longrightarrow\sf x+1=3$

${:}\longrightarrow\sf x=3-1$

$:\longrightarrow{\boxed{\purple{\bf x=2}}}$

Verification :

• Substituting the value of x :

${:}\longrightarrow\sf x+1=3$

${:}\longrightarrow\sf 2+1=3$

${:}\longrightarrow\sf 3=3$

$:\longrightarrow{\boxed{\pink{\bf LHS = RHS}}}$

Finding value of y :

${:}\longrightarrow\sf y-2=1$

${:}\longrightarrow\sf y=1+2$

$:\longrightarrow{ \purple{\boxed{\bf y=3}}}$

Verification :

• Substituting the value of y :

${:}\longrightarrow\sf y-2=1$

${:}\longrightarrow\sf 3 -2=1$

${:}\longrightarrow\sf 1=1$

$:\longrightarrow {\pink{\boxed{\bf LHS = RHS}}}$

$\huge{\therefore}$ The value of x and y is 2 and 3 respectively.
